has a fixed focal length while a zoom lens allows users to zoom in closer to a subject.
a hole that can be made larger or smaller to control how much light falls on the sensor. This will determine how light or dark the final image is.
determines how long light is allowed to fall on the sensor
replaces the film aspect on a digital camera. Using a large array of small dots, this component captures light and color information to produce what we see when looking at a photo.
This is the window that allows a user to see what image the camera will capture.
an optional device which sits above the lens, usually on the top of a camera. It can be used to lighten up a scene with a single burst of light given off when an image is taken.
Located on the top of any camera, this button is pressed to capture a photo.
Most modern digital cameras have an LCD screen to view captured images and navigate menu
these buttons allow users to control functions on the digital camera such as white balance, ISO speeds, aperture, shutter speeds, custom settings and other functions depending on the brand of the camera.
This is the storage device of any camera and allows users to view images and transfer them to a computer.
Through this component, users can transfer or copy images to a Windows or Macintosh computer
This provides life to a camera.
allows you to select different options, such as automatic mode, program mode, sport mode or macro mode.
allows manual control of the camera's focus.
used to view and change options and settings, view
pictures after they are shot, and on some cameras, as a viewfinder.
An optical defect in a lens causing it to form an image that is not sharp or that is distorted. This can take the
shape of edge distortion or a lack of sharpness.
Adobe RGB (1998)
provides a fairly large gamut of colors and is well-suited for documents that will be converted to CMYK ... Generally speaking this is the setting recommended by most photographers.
AF (Autofocus) Lock
Used to prevent autofocus operation once the subject is in focus. This gives you more creative control by allowing you to focus, compose your image, and then capture the image.
Angle of View
The area of a scene that a lens can cover.
A lens with a curved, non-spherical surface. Used to reduce aberrations and achieve a more compact lens
produced when the position of the camera lens is at its widest angle. Lines you expect to appear perpendicular are not.
taking numerous photos of the same thing using a variety of different camera settings.
Caused by even a slight movement of the camera as it records an image. Causes blurred images.
CCD Charge-coupled device
An image sensor that reads the charges built up on the sensor's photosites a row at a time.
The inability of a lens to bring all light wavelengths (particularly red & blue) into the same plane of focus, thus
causing overall blur.
The four process colors used in printing: cyan, magenta, yellow, and black. generally used to print a color separation.
Color temperature - Color of Light
A method of expressing the color content and quality of light and measured in Kelvin (K).
Depth of Field
Refers to how much of a photo is in focus when the camera is focused on the main subject.
electronic zoom where the camera interpolates the sensor readings to simulate a zoom.
Designed to provide light where the lighting on the scene is insufficient. Requires high voltage, usually obtained through batteries and a voltage-multiplying circuit which discharge a brief, intensive burst.
Exchangeable Image File - Data that is stored in jpeg and TIFF image files, such as shutter speed, date and time, focal length, exposure compensation, metering pattern and if a flash was used a the time a photo was taken.
Increase or decrease the exposure an image from the exposure automatically selected by a camera metering
Built-in digital camera meter that measures the amount of light when framing a photo and determines the best exposure.
F-numbers or F-stops
Numbers on the lens aperture ring and the camera's LCD (where applicable) that indicate the size of lens aperture. The lower the number the larger the aperture.
ISO stands for International Standards Organization and numbers such as ISO 100 or ISO 400 etc. Film was always manufactured to be at a certain ASA. Digital cameras give you the ability adjust your sensitivity to light or ISO. The higher the number, the more sensitive or faster the film.
A lens that has a shorter focal length and a wider field of view (includes more subject area) than a normal lens.
A lens which can be adjusted to a wide range of focal lengths. This allows a photographer to carry fewer lens.
Single-Lens-Reflex (SLR) Camera
Light entering the camera through the lens is reflected up by a mirror behind the lens onto a ground glass screen above. This screen is viewed through the viewfinder and a glass pentaprism which turns the image the correct way up. Other camera functions such as light metering and flash control also operate through the camera lens.
A condition in which too little light reaches the film or camera sensor.
The largest aperture (smallest F-stop) at which a lens can be set.
A true zoom. The focal length of the lens extends and retracts so an image is magnified by the lens itself.
Improper exposure causing an image to look too light.
Aa standardized technology that lets you print images from a memory card in a digital camera directly to a printer regardless of brand. No computer is necessary.
This refers to following a subject with your camera.
a two-dimensional representation of a three-dimensional scene.
A lens that has one focal length.
An additive color model that starts with black, the absence of light. Computer monitors emit a combination of three colors: red, green, and blue to create a full color display.
The intensity, or vividness, of a color.
The delay that takes place between pressing the shutter-release button and the time a photo is actually
length of time that the light capture medium is open to the light.
The fitting on a camera that holds a small portable flash.
